Pulse Output

4. WIRING

IMPORTANT

• As this is a transistor contact (insulated type),

give attention to proper voltage and polarity

when wiring.

• Do not apply a voltage larger than 30V DC or a

current larger than 0.2A in order to prevent

damage to the instrument.

• When input filter constant of the electronic

counter is large in relation to the pulse width,

the signal will decrease and the count will not

be accurate.

• If the input impedance of the electronic counter

is large, an induction noise from the power

supply may result in inaccurate counts. Use a

shield cable or sufficiently reduce the input

impedance of the electronic counter within the

electromagnetic flowmeter pulse output specifi-

cation range.

• The active pulse output (Optional Code EM)

cannot be used in conjunction with the standard

pulse output.

• When the active pulse output (Optional Code

EM) is selected, do not be short-circuit between

the P+ and P– terminals to avoid damaging the

instrument.

• When the active pulse output (Optional code

EM) is selected, the range of pulse rate must

be set to 2 pps maximum.

• To avoid communication (BRAIN/ HART)

failure, it is recommended to use the shield

cable.

Status Input

IMPORTANT

Status inputs are designed for use with no- voltage (dry) contacts. Be careful not to connect the status to any signal source carrying voltage. Applying voltage may damage the input circuit.

Closed: Less than 200 Ω

Open: More than 100 kΩ
